Respuesta :
The solubility of KCl in boiling water is 56.3 g / 100 g water So each gram of water dissolve 56.3 / 100 = 0.563 g KCl in g water
We have here 50 g water so the total amount of KCl dissolved = 50 * 0.563 = 28.15 g KCl
We have 250 g KCl so it is not dissolved completely (only 28.15 g KCl will be dissolved)
We have here 50 g water so the total amount of KCl dissolved = 50 * 0.563 = 28.15 g KCl
We have 250 g KCl so it is not dissolved completely (only 28.15 g KCl will be dissolved)
Answer:
No, potassium chloride will not dissolve completely. Only 28.15 g of potassium chloride will get dissolved.
Explanation:
Amount od potassium chloride added to 50 g of boiling water = 250.0 g
The solubility of potassium chloride in boiling water is 56.3 g/100 g water.
Amount of potassium chloride soluble in 100 g of boiling water = 56.3 g
Amount of potassium chloride soluble in 1 g of boiling water = [tex]\frac{56.3 g}{100}[/tex]
Amount of potassium chloride soluble in 50.0 g of boiling water :
[tex]\frac{56.3 g}{100}\times 50.0 g=28.15 g[/tex]
Amount of potassium chloride left undissolved = 250.0 g - 28.15 g = 221.85 g
28.15 g of potassium chloride will dissolve and remaining 221.85 g og potassium chloride will not.
